This'invention is designedparticularlyfor 1 use in connectlon with envelope opening and feeding machines such as illustrated in my applications, Serial Numbers 319,986 and 832,943,;filed November 16, 1928 and January 16, 1929, respectively, this application being a division of application Serial No. 319,986, filed November 16,1928. While the inven- 'tion will be describedpas being used in" connectionwith such machines, it is to be understood, of course, that I intend to include its use in any of the arts to which it canbe' accommodated. I An object of the present inventio'nis to provide. a magazineconstruction which is capableof adjustment so'as toaccommo'date the same'to any size or thicknessof material within the limits of the magazine construc; tion itself,'and which'is of such" universal adjustability that it can be readilyand quickly adapted for the various materials being operated upon.

A further object of the present invention is to'provide a magazine constructioncom posed of parts which may be cheaplycon} structed so'as to materially reduce'the cost of such machines, and yet which is eflicient and practical inoperation.

azine construction which is provided with an adjustable guide plate which'may be so set as to insure proper feeding ofthe stacked articles one at a time from the magazine.

A still further object is'to provide a guide plate for magazine constructions which yieldingly engages the edges of the material to be treated and thereby yieldably supports the stackedarticles within the magazineand' permits the articles to" be fed from the magazine without mutilation. p

Other advantages andobjects will be clean ly apparent from the following description,

fall within-the spirit or scope of my inven tion,-as"outlined in the attached claims.

Referring to the accompanying drawings forming part hereof and in which a preferred embodiment of my inventionis illus trated, Fig. 1 is a plan View of my invention: Fig. 2' 1s a vertical sectional view taken" along the line A-A of Fig. 1Q V Fig. 3 is a rear view of Fig; 1. 9 Referring more particularly to the draw C ing, the invention is illustrated as beingusedf in connection with a machine such as shown in myapplications, Serial Nos. 319,986 and 332,948, filed November 16, 1928 and J anuary16, .1929, respectively, in which the machine is illustrated as comprising spaced side walls which arehere numbered 1 and 2, between? which is journalled the feed rollj3 which delivers the article being operated upon to the transfer rolls 1 and5, andthence to the roll 6 by means of which the material isfed against the face'of'thedefiecting plate 7, all 'of which is illustrated in said a-pplication and which therefore requires no further illustration or description. I

The sidewallsl and 2areprovided at their upper edges with recesses illustrated at 8 on one side ofthe machine, it being. understood that the opposite side of the machine is of the same construction, and on the top edge of I thevside' walls 1 and 2 I secure triangularly shaped brackets 9 and 10 which are provided ,at their front lower edges with bearingsll whichproject into'the recesses 8 in the top edges ofithe frames. The brackets 9 and 10 and 2' by means of bolts 12 or other suitable fastening means, and while I have here indi cat'ed thatthe brackets 9 and 10 are of cast stoodthat these parts may be formed of stamped sheet metal or other suitable 'material. The brackets 9and'10 at the front of the magazine carry spaced'longitudinally extend-f 7 -ing rods118and 14 which are secured .to the brackets' 9and '10 by means of screws 15 or other suitable fastening means, and at spaced intervals along thehorizontal rods 13and h 14 I provide vertical rods 16,17 and 18, su t ably secured to the rods 13 and '14, as indispaced notches 29 located immediately below,

cated at 19. The rods 16, 17 and 18 may be secured to the rods 13 and 14 by spot welding, rivets, screws, or other suitable fastening elements, and they form in reality a reticulated frame which comprises the front wall of the magazine construction.

The vertical rods 16, 17 and 18 are of such a length that the lower ends terminate at a point slightly above the upper edges of the side frames 1 and 2, and the feed roll 3is so located that its periphery extends slightly above the edges of the frames 1 and 2, thereby leaving a space between the lower ends of the vertical rods 16, 17 and 18, and the feed roll 3.

- The bearings 11 on the brackets 9 and 10 are located in this space between the vertical rods, and the feed roll 3, and in the bearings 11 are journaled trunnions 20 and 21 which extend from opposite ends of the guide blade 22, sothat the guide blade 22 is rotatably supported between the vertical rods and the feed roll 3, and in reality forms an extension of the front wall of the magazine construction. .In order to adjust the guide blade. 22 to accommodate materials of varying thicknesses, I provide a screw threaded stud 23 on the horizontally extending rod 13 intermediate the ends thereof and on the guide blade 22 I secure a vertically extending arm 24 by means of rivets 25 or other suitable fastening means, and the arm 24 is provided at its upper end with an opening 26 which is adapted to pass over the screw-threaded stud 23'projecting from the rod 13.

Encircling thescrew-threaded stud 23 is a spring 27 having an end thereof bearing against the horizontal rod 13 and the opposite end bearing against the arm 24, andon the opposite side of thelarm 24 I provide a thumb nut 28 threaded on the stud 23 and bearing against the arm 24. From the foregoing it will be seen that the spring 27 normallv urges the arm 24 away from the brackets 9 and 10, and that by adj ustingthe thumb 28, the guide blade'22 can be rotated so as to material from the magazine and to prevent any possibility of the articles becoming engaged between the blade 22 andthevertical rods 16, 17 and 18, I provide the blade with the ends of the rods 16, 17 and 18, so that the upper edge 30 of the blade 22 is above the lower end of the vertical rods 16, 17 and 18, thereby rendering it impossible for an envelope or enclosure to become engaged between the blade and the vertical rods, and insuring proper feeding of the envelopes from p the magazine. I

It is further to be noted from the foregoing thatthe blade 22 yieldingly contacts with the stacked .articles'in the magazine, so thatthe commodate the sidewalls of the magazine construction to materials of varying thicknesses.

From an' inspection of Fig. 2, is will be seen. that the lower edge of the plates 30 is inclined upwardlytoward the front of the ma chine, the purpose of which is to permit.

mounting of the feed roll 3 so that its pe riphery is in substantially the same plane as the top edge of the frames 1 and 2.

Carried on each adjustable plate 30- are brackets 33 and 34 which consist of flat sheet metal strips which are provided with; elon- V gated openings or slots 35 and terminate at their forward ends in rearwardly bent extensions 36 and 37, which terminate in vertically extending heads 38 and 39 which are likewise and 41.

From an inspection of'Fig. 1 it will be seen that the extensions 36 and 37 are bent so asto incline rearwardly with reference to theside plates30 and are of such angularity with reference to theside plates 30 that they will abut and support the edge of an envelopein a'fiattened condition, as indicated by the dotted line B, or they may receive the 31 l provided with elongated slots 40 edge of an envelope when in its closed con,-

dition, as indicated by the dotted line C.

In order to adjust the brackets 33'and 34 on the side plates 30, I'provideheaded screws 42 and 43 which are adapted to receive thumb '211 nuts 44 and 45, so that the brackets 33 and 34 can be clamped between the thumb nuts and the bolt head, as clearly indicated inFig. 1 These bolts are passed through the elongated slot 35 so that upon loosening the thumb nuts 44 and 45, the brackets 33 and 34 may be adusted to accommodate envelopes of varying sizes. 3

In order toenable the mechanism to receive stacks of varying heights of material, and

to adjust the position in which the envelopes or other material are to be supported in the ma-gazlne, I provide the vertically adjustable back plates 46 and '47, which are provided with screw threaded studs'48 and 49, proj ecting through the elongated slots 40 and 41 1n the headed portions 38 and 39 of the brackets 33 and 34, and on the studs 48.and

49 are threaded. the thumb nuts. 50 and 51.

It will be apparent, therefore, that by a loosening the thumb nuts 50 and 51, the back plates 46 and 47 may be adjusted to any suitable height, after which they can again be locked in place.

From the foregoing description, it is be lieved to be obvious that the side plates 30 can be adjusted on the rod 31 to accommodate the magazine to envelopes or other material of varying lengths, and that by adjusting the brackets 38 and 34 envelopes or other material of varying width can be accommodated, and finally, by adjusting the back plates 46 and 47, it is possible to accommodate material of varying heights within the magazine. Furthermore, it is seen that by producing such adustability the brackets 33 and 3a and the back plates 46 and L? can be so adjusted as to vary the angularity of the envelopes in the magazine, such as indicated at D in Fig. 2, thereby insuring proper supporting of the envelopes so that they can be fed by the feed roll 3.

Additionally, it will be seen that I have provided a practical, eficient, and inexpensive construction which is capable of handling materials of practically all sizes and shapes with in the limits of the magazine. itself.
